More details about the The Palomar Knot
Uses: The Palomar Knot is a simple knot for attaching a line to a hook, or a fly to a leader or tippet. It is regarded as one of the strongest and most reliable fishing knots.
Tying it: After the loop is passed through the eye, an overhand knot is tied with the loop. The loop is then passed over the hook and the knot is tightened down.
Advantages: It is recommended for use with braided lines. With a little practice the Palomar is a knot which can be tied in the dark.
Alternative: This animation shows the loop wrapped against the shaft of the hook. However, most authorities recommend that this loop be pulled off the hook and down against the rest of the knot. The effect is that this leaves the hook free to rotate in the knot.
Disadvantages: When tying this knot, the fly or hook has to pass through the loop which can be awkward and necessitates making the loop large enough.
